Tic disorder is a problem in which a part of the body moves repeatedly, quickly, suddenly and uncontrollably. Tics can occur in any body part, such as the face, shoulders, hands or legs. They can be stopped voluntarily for brief periods. Sounds that are made involuntarily (such as throat clearing, sniffing) are called vocal tics. Most tics are mild and hardly noticeable. However, in some cases they are frequent and severe, and can affect many areas of a child's life.

Tic disorder is common in children. Tics commonly occurs between the age of 7 to 10, but may sometime start as early as 2 or 3 years old. Tic disorders have a genetic link so they tend to ruin families.

Tic disorder is classified as follow:

Temporary tics: affect up to 10 percent of children during the early school year. Temporary tics can go away by themselves

Chronic tics: don’t go away and can last one year or more. Chronic tics affect less than one percent of children and may be related to a special, more unusual tic disorder called Tourette's Disorder. Children with Tourette's Disorder have both body and vocal tics (throat clearing). Some tics disappear by early adulthood, and some continue. Children with Tourette's Disorder may also have problems with attention, and learning disabilities. They may act impulsively, and/or develop obsessions and compulsions.Through a comprehensive evaluation, often involving pediatric and/or neurologic consultation, a child and adolescent psychiatrist can determine whether a youngster has Tourette's Disorder or another tic disorder. Treatment for the child with a tic disorder may include medication to help control the symptoms and habit reversal training; a behavioral therapy. The child and adolescent psychiatrist can also advise the family about how to provide emotional support and the appropriate educational environment for the youngster.

Tic disorder and ADHD:

Approximately half of children with tics also have ADHD. In children who develop tic disorder and ADHD, the ADHD usually develop 2 to 3 years before the tics.

There has been some controversy over whether stimulants, the most common form of medication therapy for ADHD, worsens or even causes tics. Studies indicate that most children with co-occurring tics and ADHD do not experience an increase in tic severity while on low to moderate doses of stimulants. However, there does appear to be a small proportion of children for whom this is a problem. It is not clear if the stimulants actually cause the tic or if the stimulants trigger tics that were already pre-existing, but not yet obvious. It is also possible that tic disorders may look similar to ADHD in their early stages. So the tic would have developed whether or not the child had been treated with stimulants.
